    • An ultrasonic flaw detector device including axial and circumferential fixed tracks located in a space defined between a pressure vessel of a nuclear reactor and a heat insulating wall surrounding the vessel and arranged axially and circumferentially respectively of the pressure vessel of the nuclear reactor. A rotary track is located at a junction of the axial fixed track and the circumferential fixed track and moved in rotary movement by a chain and has its angle of rotation restricted by a pair of stoppers. A carrier member supporting an ultrasonic probe is moved on the tracks to effect ultrasonic flaw detection to detect any flow that might be present in the pressure vessel. To transfer the carrier member from the axial fixed track to the circumferential fixed track, the carrier member is first transferred from the axial fixed track to the rotatable track, and after the rotary track is rotated, the carrier member is transferred from the rotatable track to the circumferential fixed track.
    • 一种超声波探伤装置,其包括位于核反应堆的压力容器之间的空间中的轴向和周向的固定轨道,以及围绕容器的绝热壁,并分别轴向和周向地布置在核反应堆的压力容器中。 旋转轨道位于轴向固定轨道和周向固定轨道的接合处,并通过链条旋转运动,并且其旋转角度受到一对挡块的限制。 支撑超声波探头的载体部件在轨道上移动以实现超声波探伤以检测可能存在于压力容器中的任何流动。 为了将载体构件从轴向固定轨道传递到周向固定轨道,承载构件首先从轴向固定轨道传递到可旋转轨道,并且在旋转轨道旋转之后,承载构件从可旋转轨道传递到 圆周固定轨道。
